For an all around tire, I liked the 33x10.50 AT/KOs I ran on my '85:

Two downsides I found was that on gravel the tread tends to pick up ad throw lots of rocks, would be a problem with most any AT tread though. With MTs, I find almost no rocks thrown up under the truck. Also that tighter tread pattern seemed more prone to picking up road debris and causing flats. I think I had two flats on those ATs over their lifetime compared to none for two sets of BFG MTs.

But for pavement and in snow they were awesome tires.
